Overview
A significant security vulnerability, identified as CVE-2025-65235, has been discovered in OpenCode Systems USSD Gateway OC Release 5 Version 6.13.11. This vulnerability is a SQL injection flaw located within the getSubUsersByProvider function, specifically affecting the ID parameter. This could potentially allow malicious actors to execute arbitrary SQL commands, leading to unauthorized data access, modification, or even system compromise.
Technical Details
The SQL injection vulnerability exists because the getSubUsersByProvider function fails to properly sanitize user-supplied input (the ID parameter) before using it in a SQL query. An attacker can inject malicious SQL code into the ID parameter, which is then executed by the database server. The lack of proper input validation is the root cause of this issue. Exploitation could involve crafting a specific URL or API request with malicious SQL payloads.
CVSS Analysis
Currently, the CVSS score for CVE-2025-65235 is listed as N/A. While the severity is also listed as N/A, the nature of a SQL injection vulnerability suggests a potentially critical impact. A full CVSS analysis, once available, should be reviewed to determine the precise risk level. Without a CVSS score, judging the precise impact is difficult, but SQL injection vulnerabilities are generally considered high risk.
Possible Impact
The potential impact of this SQL injection vulnerability is severe. A successful exploit could lead to:
- Data Breach: Access to sensitive user data, including usernames, passwords, and other personal information.
- Data Modification: Modification or deletion of critical system data, leading to service disruption.
- System Compromise: Complete takeover of the database server, potentially allowing the attacker to execute arbitrary commands on the underlying operating system.
- Denial of Service: Overloading the database server with malicious queries, leading to a denial of service for legitimate users.
Mitigation or Patch Steps
To mitigate the risk posed by CVE-2025-65235, the following steps are recommended:
- Apply the Patch: Immediately apply the security patch released by OpenCode Systems. Check their official website for updates. (As of this writing, a patch status is unknown.)
- Input Validation: Implement robust input validation and sanitization on all user-supplied data, especially the
IDparameter used in thegetSubUsersByProviderfunction. Use parameterized queries or prepared statements to prevent SQL injection. - Web Application Firewall (WAF): Deploy a WAF to detect and block malicious SQL injection attempts. Configure the WAF with rules to identify and prevent common SQL injection patterns.
- Least Privilege: Ensure that the database user account used by the USSD Gateway has only the necessary privileges to perform its functions. Avoid granting overly permissive access.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities.
